Abstract: 404,196. Trimmings. BROOKE, A., 37, Ford Street, Coventry. May 23, 1933, Nos. 14837 and 16429. [Class 141.] Beadings, edgings, drip and cornice mouldings, and the like, for attachment to the bodies of motor and other vehicles, are provided with a series of attachment devices permanently secured thereto and consisting of short spikes formed either with barbed points or as prongs adapted to spread apart when driven home. The spikes d may be fixed at intervals to a metal strip e embedded in the moulding a, as shown in Fig. 2, and such spikes may be made separately and welded or otherwise secured to the strip e, or they may be made integral with the strip by stamping them out of the edges thereof, as shown in Fig. 5, or by punching them out of the body of the strip, as shown in Fig. 7. Alternatively, the attachment devices may be formed from a piece of wire or metal strip bent upon itself, as shown in Fig. 8, so as to form two prongs f having bevelled points f <1>. The prongs f may also be barbed. Where the backing to which the moulding is attached comprises material g of shallow depth mounted on a metal foundation h, as shown in Fig. 11, the prongs f not only spread when driven home but are deflected when they meet the metal foundation. In the case of metal beadings, the attachment devices may be cast in the beading, or the face of the beading may be provided with an undercut channel a<1>, Fig. 10, and the head f of the attachment device is secured therein by rolling over the lips a<2> of the channel. The attachment devices may also be welded or soldered to a metal moulding, or the latter may be perforated to receive the attachment devices. Members f with bevelled points may also be stamped out of the opposite edges of a metal strip as in the case of the barbed spikes shown in Fig. 4, and such members, after being bent at right angles to the strip, are twisted, as shown in Fig. 12, so that they spread apart when driven home. The second Provisional Specification describes also the fixing of the attachment devices in mouldings of fabric, rubber, wood, and the like, and the formation of the devices as integral parts of a metal moulding.

In a example, a 48% aqueous solution of hexamethylene diammonium adipate is polymerized in an autoclave in presence of 0.3 % mol. (based on the adipate salt) of a 25% aqueous acetic acid solution and sufficient aqueous solution of polyethylene ether glycol to provide 15% by weight of glycol based on the weight of polyhexamethylene adipamide.  The compositions are spun into filaments (see Division B5). Specifications 576,647, 639,893, 902,905 and 902,907 are referred to.ALSO:Yarn, tow, floc, staple, cord or fabric having antistatic properties is comprised of oriented, melt-spun filaments or fibres of poly amide, e.g. nylon having distributed therein elongated particles (0.05-0.7 m  dia. x more than 3m  length) of a poly(alkylene ether) glycol having 2 or 3 carbon atoms in the alkylene group or groups and a molecular weight at least 600.  The polyamide filaments or fibres have an N.M.R. peak ratio of at least 1.5 and contain at least 1% of the poly (alkylene ether) glycol.  The filaments or fibres, before or after making up into a yarn or fabric, may be scoured or extracted with hot water so that a proportion of the poly (alkylene ether) glycol is removed and voids are formed in the filaments.  This increase the covering ability and soil-hiding properties of the yarns or fabrics.  The antistatic filaments may be used alone or in conjunction with other filaments to form mixed yarns e.g. 10% units static nylon filaments with 90% normal nylon filaments.  The filaments may be heat-set, twisted or crimped and may be formed into any type of knitted, woven or felted fabric.  In an example, drawn filaments spun from nylon 66 containing 15% of polyethylene glycol are woven into a fabric which is scoured in boiling water for 1 hour.  The scoured fabrics contain 2-8% polyethylene glycol and the fibres contain elongated voids of circular cross-section.  Specifications 576,647, 639,893, 902,905 and 902,907 are referred to.

Abstract: 1,115,689. Gas liquefaction process. MESSER GRIESHEIM G.m.b.H. 4 April, 1967 [5 April, 1966], No. 15335/67. Heading F4P. Most of the refrigeration required to liquefy compressed feed gas, e.g. natural methane, is met by dividing the feed stream leaving a drier 11 into a major stream 12 which after being cooled in an exchanger 17 is expanded without liquefaction and to above atmospheric pressure in a turbine 37 coupled to a compressor 45 supplied with at least some of the feed gas, and into a minor stream 13 which after being freed of condensables in an absorber 15 is cooled and liquefied in exchangers 17, 21 traversed by counterflowing turbine-expanded major stream and is then sub-cooled in an exchanger 23, expanded to atmospheric pressure in reducing valves 25, 28 and fed to a storage tank 29 from which vapour is withdrawn by a blower 31 and returned through a line 32 through exchangers 23, 21, 17 which are also cooled by flash gas from valve 25 passing through a line 30. The minor stream leaving expansion valve 25 is fed into a separator 26 and liquid withdrawn therefrom through a line 27 is sub-cooled at 33 by a portion of the liquid being expanded at a valve 27B and the so-vaporized portion is then fed into line 32. The minor and major feed streams leaving the cold end of exchanger 17 are freed of liquid C 2  hydrocarbons in drums 18, 34 and said hydrocarbons are fed to a drum 39 together with the expanded major stream leaving turbine 37. Overhead gas in drum 39 is fed through a line 42 to the compressor 45 and discharged into a consumer line 46, whilst condensate in drum 39 is in part fed through a line 43 to line 42 and in part through a control valve 50 to the tank 29, from which liquefied gas is withdrawn by a pump 52 vaporized at 53 and fed to a consumer line 54. In a modification compressors 45A, 45B, Fig. 2 (not shown), driven by turbines 37A. 37B arranged in two stages compress already pressurized feed gas prior to its entry into the drier.
